Answer:
Although there are two correct choices for the question: The EEC (European Economic Community) permitted what after World War II?, the better suited one would be A: It allowed nations to trade freely with one another.
Step-by-step explanation:
The answer is explained through the initial purpose and the history of the EEC. The EEC, also known as the European Economic Community, was born after the end of World War II, in 1957, with signing of the Treaty of Rome betwen its six initial forming nations: Belgium, France, Italy, West Germany, Luxembourg and the Netherlands. Its purpose was to create economic integration, a common market and customs union. This community, was later renamed as the EC (European Community) after the birth of the European Union in 1993. It is true that during the EEC, there was free traveling of people within the nations in the pact, but the first objective was economic, and migration came as a response to the economic movement brought on by the EEC. This is why the better choice is A and not B.
